To an whom it mag] concern:

Be it known that I; Tnoiinx's JEROME cos;

a citizen of the United Stateaiand resident Kings and" State of New Yorlnhave' in- I rented certain new and useful m r vements in Exhibitors", of WlUClIthG' following is specification. z

This invention relates to devices adapted for the exhibition of signs" and advertising matter of various descriptions! Oneobje'ct of the invention is to produce a simple and eiiicient device for thepurpose stated, which admits of being manufactured at low cost. I p

A further object is the production of an exhibitor wherein the signdisplaying member can'be quickly and conveniently changed;

Another object is to provide an improved actuating mechanism for the exhibitor; capable of driving additional sign -'ca rrying members. l I

With these objects in view," the invention consists in the improvements and combinations of parts hereinafter described and pointed out inflthe appended claims.

In the drawings illustrating the preferred form of the invention Figure 1 isa' front view of the exhibitor, some parts being; re moved; Figs. 2 to 7 inclusive are vertical cross sections, taken respectively'from' the lines AA,v 13-43; C -C3, DI'D, E+E and F+F of Fig. l; and Fig. 8 is a left-hand side view of Fig. 1 partly broken away.

In these views, the numeral .10 represents the right-hand side frame of the device, and 11 is an intermediate frame. p

A drivingshaft' 13, which may be driven either by an'electric motor or fro In" a caraxle. is journal'ed' in: bearings 14:, 15' carried by the frames 10, 11' on a substantially central line within the lower part of the device. This shaft has a gear-Wheell7, fixed thereon and meshing, witha loose gear 18, mounted on a shaft 19, directly above. named, shaft 19 is revolubly" supported by bearings 20, 21, also carried by'kthe frames 10, 11. The fixedgear 17 further enga es with a pinion 22, secured to a shaft 23,-journaled in similar bearings 24, 25 of frames 10',

the driving-shaft 13".and'the' said shaft19. Another pinion 26,I also secured to the'rear shaft 23, engages a gear 28,:similarly loosely mounted on saidshaft 19. Due to thexae- The latter tions; as .more fully hereinafteradescribed.

A hub 35, pinned centrally on the shaftl9' between the aforesaid rimsfl29gfl30 is pro-- vided with'a pa ir of arms 36, 37 ,carrying at their outer. ends a shortshaft, 38, to the extremities of which are securedgpawls 39, 10. .The' pawl .40 has an arm 41 that carries a pin 42, to which is anchored one end of a spring-5 4'3; The other end of spring 13 is attached; asat. 14;, between the arms 36, 37. The tendency ofsaid'spring is to maintain either the pawl 39 orthe pawl 40 in engage ment with the corresponding; ratchet teeth, 31 or 32' as the case may be, when the arm 41 passes its neutral central position.

Adjacent to'the, bearing 20 on the shaft 19, i

is secured a pinion 47, which meshes with a gear-wheeled,rotatable on a stud 49, which latter'isqfixedly held in; a boss v5'0 of the frame 10. A hub 51 connects the gear; 48 to another pinion 52, engaged by a coacting gear 55, which is fixed to a shaft 56', sup; ported in journals/57, 58' on the frames 10, 11. A hub 5'9, having spaced arms 60, 61 is secured to the shaft 56, for instance? by meansof a pin,- as shown. The ends ofthe arms 60 61 are provided with flat springs 62; 63 one on each, which springs are disposed oppositely one'to theother.

When, for example; the gear 18 drives the shaft 19, through the agency of pawl 40 in engagement with ratchet-tooth32, the shaft 56 is rotated by the gears 41?, 48, 52, 55, thereby causing the arms 60, 61 to travel in a circular path with shaft 5'6, around to the opposite side; until" the spring 68 strikes thepaw'l 39, bringing the latter into contact with the ratchet-tooth 31am arm- 36. X The shaft 19 is then turned in the opposite di-;

rection, which also reverses the motion of the shaft 56, so that thee arms 60, 61 return to the other side, in position to ,reverse the cycle again. The ratioofthe changegears 17 18 and 52-,55 predeterminesjthe number meanness; i 51 6 w e-r s e provided therefor.

tively above and below the said shaft. Sprocket-wheels 70, 71 are held by screws, or other suitable means,'to the said pinions '68, 69. Both the intermittent pinion 68 and its sprocket-wheel 70 are rotatably carried on a stud 72, while the other intermittent pinion 69 and its sprocket-wheel 71 rotate on a stud 73. The studs 72, 7 3 are held in bosses 7d 75 of the frame 11.

. A sprocket-chain 76 runs from the sprocketwheel 70 over intermediate sprocket-wheels 77, 78, secured respectively to shafts 79, 80

These shafts are journaled at one end in bearings 83, 841 on frame 11, and at the other end they are similarly journaled in an outboard side frame (not shown). Clamping-rolls, each composed of two parts, 85, 87 and 86, 88 respectively, are secured to the shafts 79, 80, one two part roll to each shaft. The parts 85, 86 are fixed on their respective shafts, While the parts 87, 88 form caps that are held to 85, 86 by elastic ring clips 89, 90.

'91 represents a curtain (omitted in Fig. 1)

of paper or cloth, having denoted thereon the reading or advertising matter to be eX- hibited. This curtain is clamped between the meeting edges of the parts 85, 87 and 86, V 88 that compose the clamping-rolls and which are suitably beveled to receive the ends of the curtain between them. As an extra precaution, to prevent slipping, the

ends of the curtain may be pinned to the opposite beveled faces of the fixed parts 85 and 86,, as indicated in Figs. 6and 7. The curtain is wrapped so as to wind and unwind alternately from one clamping-roll to the other, and it is made to pass also over an idler roll 92, loosely mounted on a shaft 98, hereinafter referred to. From the sprocket-wheel 71 also runs a sprocketchain 95, to and around another pair of sprockets 96,97, secured respectively to shafts 98, 99 which are journaled at one end in bearings 100, 101 on the frame 11. At the other end these shafts are supported in outboard bearings (not shown). A second curtain 102, similar to 91, is anchored at its ends to and within two-partrolls 105, 106, constructed like the rolls 85, 87 and 86, 88 previously described. The curtain 102 also passesover an idler roll 107, mounted loosely on the shaft 79. The ends of the shafts for 'the said rolls are provided with coupling members 108, so that any desirable number of curtain carrying rolls can be connected up in series, and thus be driven from one unitary actuating mechanism.

The curtains and rolls are inclosed in acasing 109, the fronthalf of which has an aperture or sight-opening 110, covered with some transparent material, permitting the matter inscribed, printed or depicted on the curtains to be readily viewed. This casing may consist of a plurality of parts hinged stance from the roll 8587 while it winds up on the roll 86, 88. Meanwhile the intermittent pinion 69 remains quiescent and the rolls 105, 106 are accordingly inactive, thus keeping the curtain 102 during a corresponding period of repose in front of the opening 110. In the same manner the conditions, of the rolls 85, 87, 86, 88 and 105, 106 are reversed, when the intermittent gear 67 engages the intermittent pinion .69, leaving the first mentioned rolls inactive. Thus, it is seen that one curtain always is traveling while the other curtain is at rest. When the direction of motion of the shaft 19 is reversed in the manner hereinbefore described, the relative rotation of the rolls is obviously also reversed. This is timed to take place when the available length of ourtain has been wound up on one set of rolls and unwound from the other set.

Having described my invention what I desire to secure by Letters Patent and claim is 1. An exhibitor comprisinga plurality of curtains adapted for travel in opposite directions, rolls on and off which said curtains respectively wind and unwind, a driving shaft, a reversible shaft, loose gears revolved in opposite directions on said reversible shaft from said driving shaft, ratchets moved by said loose gears, pawls secured to the reversible shaft alternately acted upon by said ratchets, a reverse controlling shaft geared with the reversible shaft, said con trolling shaft having arms operating to throw said pawls successively into engagement with their respective ratchets and thereby drive the reversible shaft alternately in opposite directions, and mechanism intermittently and alternately connecting the reversible shaft with one or another set of said rolls whereby one curtain is moved while another is at rest.
